Another week without Richard Marshall starts now

The Dolphins return to practice in preparation for the Tennessee Titans game on Sunday. They'll be on the practice field inside of 30 minutes.

Don't expect Richard Marshall to be there -- today, tomorrow or this week.

A source close to Marshall tells me the Dolphins cornerback who has been battling back issues is still not ready to practice. He has missed four games and has not played since Sept. 30.

The Dolphins are not surprised by this as Tuesday they signed former Cowboys, Ravens, and Raiders cornerback Bryan McCann.

McCann beat out a couple of other players who tried out, including former Dolphins cornerback Jonathan Wade.

By the way, you can bet that Marshall will miss the next two games. Becasue he's not practicing this week, he obviously is not playing against the Titans. And he's not playing against the Bills because that game is on a Thursday -- after a short week or preparation -- and that won't give Marshall enough time to gear up for the game even if he is fully healthy again, which also is uncertain.

So the earliest Marshall is back in the lineup would be Nov. 25 against Seattle.

[Update: The Dolphins overall are a relatively healthy team. Marshall and LB Koa Misi are the only players not at practice today.]
